Binary neutron-star (BNS) mergers can be accompanied by multi-messenger emissions, including gravitational wave (GW), neutrino, and electromagnetic (EM) signals. Some fraction of BNS mergers may result in a rapidly spinning magnetar as a remnant, which can enhance both the EM and neutrino emissions. I will discuss the possible neutrino and EM signatures from such systems.
I will also briefly discuss the possibility and prospects of performing GW-triggered stacking searches for high-energy and ultra-high energy neutrinos from BNS mergers in general, at IceCube-Gen2, using the next generation of GW detectors.
Short Biography
Mainak Mukhopadhyay is a Research Associate at Fermi National Accelerator Laboratory (Fermilab) and an Associate Fellow at the Kavli Institute for Cosmological Physics (KICP) at the University of Chicago. Prior to his current position, he was a Postdoctoral Research Scholar and an IGC Fellow at the Institute for Gravitation and the Cosmos (IGC) at Penn State. His work explores multi-messenger signatures of high-energy astrophysical phenomena, including astrophysical neutrinos, gravitational waves, photons, and dark matter. He is also interested in understanding the interplay between classical and quantum degrees of freedom, particle production, backreaction, and topological defects, in the context of early universe cosmology. He earned his Ph.D. in Physics from Arizona State University, where he studied neutrinos and quantum fields in the Universe.
